I'm wondering how many frame per second are shown during Hollywood feature films, like Star Wars? I know 30/sec. is the norm around here on th desktop, but what would a really good Short require? = )

For film, 24 frames per second. For television, 29.97 fps (NTSC standard) or 25 fps (PAL standard).

Ugh !! SMTE conversions. bikermouse makes the sign of the vampire cross.(why couldn't they all use the same frame rate ? - it would have been so much simpler.)

i would set to 29.971 just to bust some balls

I've always heard that film cell-based animation was always shot two frames ber cell, so it was effectively 12 fps, and computer animation was done the same way, thus 15 fps. I do know if you do ut this way it doesn't look too jerky, and you halve your render times!

just to be awkward I do my animations at 50fps, makes for a really smooth ride :)

So... Silly question... when I watch a film on telly... I get one extra frame every second!? (PAL-UK) How the blinkin' flip do they make up the extra frame? Or maybe the film just gets shortened by 1/25... ie a 90 minute film last 3.6 minutes less time when shown on TV? Ooops... OT. H:)

Or maybe the film just gets shortened by 1/25... ie a 90 minute film last 3.6 minutes less time when shown on TV? <<< Correct. Films in Euopean TV run 4 percent shorter than on film or in US TV. [NTSC 30fps is far enough from 24 to be noticeable, so there is an adjustment to make the film take the same length of time... showing some frames (well, some fields) twice]

Advertising and intermission times? = )

UK tv has less ad breaks than US tv, having an ad break within 5 minutes of the opening titles is crazy. Rob

How is the UK schedule? = )

In the early decades of tv the Vacuum tube B&W sets used the voltage pulse sent out by the AC power. US grids have a cycle of 60Hz and PAL countries are 50Hz where the generators in the power stations turn 50 times a second. The voltage going up to 220v (UK), then down to zero volts on its way to 220V in the other direction provided the jolt of electric power these tvs needed to get the CRT to display one FIELD. Two fields each 312 lines (PAL) make one frame. Eyes cant see past 25ish frames in a second so motion picture cameras only go to 24ish a sec to save film. Just trying to find a thread I didnt finnish reading.
